Abstract
A regularization of Euclidean (super-φ3)4 on a finite four-volume Δ with UV cutoff k is given and integrability of the interaction is proven. The regularized model is shown to satisfy physical positivity if the UV cutoff is appropriately chosen. Symmetry Ward identities are rigorously derived (up to surface terms).
